After hunting around, I think I am going a different direction. I may be able to use my existing 35 remington die, or my existing 7.62x39 die, which will give me the advantage that the bullet seater is already attached. I think. I've got to look at the .35 Rem to see if it has enough to ream out, otherwise I'll sacrifice my 7.62x39 die. Obviously I'll need to drill out the pilot hole a small amount, but that is an easy enough task.

If this works, that is. I'm going to take my sweet time with the reamers
